DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1 to 3, an exercising device in accordance withthe present invention comprises a frame (10), a seat (15), two pedals(16), a housing (30) and an exercising mechanism (20). The frame (10)has a supporting stand (13) with two ends, a front leg (11) and a rearleg (12). The front leg (11) and the rear leg (12) are attachedrespectively to the ends of the supporting stand (13). In a preferredembodiment, the front leg (11) has a height shorter than that of therear leg (12) to make the supporting stand (13) inclined relative to ahorizontal level. In addition, the frame (10) further comprises a bottomstand (14) securely attached to the front leg (11).

The seat (15) is attached to the supporting stand (13) to support a useron the frame (10). In a preferred embodiment, the seat (15) is slidablymounted on the supporting stand (13) and has a bore (151). Thesupporting stand (13) has multiple holes (131) arranged in a line andselectively aligning with the bore (151) in the seat (15). A pin (155)extends through the bore (151) in the seat (15) and into one of theholes (131) in the supporting stand (13) to hold the seat (15) inposition relative to the supporting stand (13).

The pedals (16) are pivotally attached to the bottom stand (14) toconnect to the front leg (11) through the bottom stand (14).

The housing (30) is connected to the front leg (11).

With further reference to FIG. 4, the exercising mechanism (20) ismounted inside the housing (30) and on the bottom stand (14). Theexercising mechanism (20) comprises a base (21), two brackets (22), arotating axle (23), a torsion spring (24), a flywheel (25), a resistantdevice, a pulling rope (29), an adjusting button (28) and a first grip(291). The base (21) is securely attached to the bottom stand (14) toconnect to the front leg (11) through the bottom stand (14). Thebrackets (22) are mounted on the base (22). The rotating axle (23) isrotatably mounted between the brackets (22). The torsion spring (24) isattached to one of the ends of the rotating axle (23) to provide arecoil force to the rotating axle (23). The flywheel (25) is rotatablyattached to the rotating axle (23) in a unidirectional manner. In apreferred embodiment, a unidirectional bearing (252) is mounted betweenthe rotating axle (23) and the flywheel (25) such that the flywheel (25)rotates relative to the rotating axle (23) when the rotating axle (23)rotates in a specific direction and rotate with the rotating axle (23)when the rotating axle (23) rotates in a reverse direction.

The resistance device is mounted between the base (21) and the flywheel(25) to provide a resistance to the flywheel (25). In a firstembodiment, the resistance device comprises a resistance belt (26) and aresilient member (262). The resistance belt (26) is mounted around theflywheel (25) and has a first end securely attached to the base (21) anda second end. The resilient member (262) preferably is a spring and hasa first end attached to the second end of the resistance belt (26) and asecond end. With the resistance belt (26) mounted around the flywheel(25), the resistance belt (26) can provide a resistance to the rotationof the flywheel (25) with the friction between the resistance belt (26)and the flywheel (25).

The adjusting button (28) is rotatably attached to the housing (30) andconnected to the resistance device with a cable (271). In the firstembodiment, the cable (271) is connected to the second end of theresilient member (262). When the adjusting button (28) is rotated, theresilient member (262) will be pulled or released so that the frictionbetween the resistant belt (26) and the flywheel (25) is changed.Accordingly, the resistance applied to the flywheel (25) and provided bythe resistance device can be adjusted by means of rotating the adjustingbutton (28).

The pulling rope (29) has a first end reeling around the rotating axle(23) and a second end extending out of the housing (30). The first grip(291) is attached to the second end of the pulling rope (29).

Furthermore, the bottom stand (14) has a through hole (145) and a notch(143) communicating with the through hole (145). The front leg (11) hasa through hole (112) and a notch (114) communicating with the throughhole (112) in the front leg (11). As shown in FIGS. 1 and 8, a resilientrope (40) is attached to the through hole (145) in the bottom stand (14)and has a distal end. A second grip (42) is attached to the distal endof the resilient rope (40). In another embodiment, the resilient rope(40) is attached to the through hole (112) in the front leg (11). Inuse, with reference to FIGS. 1 and 6, the pin (155) is detached from thebore (151) in the seat (15) to make the seat (15) slidable along thesupporting stand (13). The user sits on the seat (15), holds the firstgrip (291) by hand and steps on the pedals (16). Then, the user can pullthe pulling rope (29) to release it from the rotating axle (23) and toextend out from the housing (30). At this time, the rotating axle (23)will be driven to rotate, and the flywheel (25) will rotate with therotating axle (23) and the torsion spring (24) will be twisted tightly.During the rotation of the flywheel (25), the resistance belt (26) willprovide a resistance force to the flywheel (25) against the pullingforce provided by the user, such that a training effect to muscles onthe arms and legs of the user is achieved.

When the user releases the force applied to the pulling rope (29), thepulling rope (29) will reel onto the rotating axle (23) automaticallywith the recoil force provided by the torsion spring (24). With thearrangement of the unidirectional bearing (252), the flywheel (25) willnot rotate with the rotating axle (23) while the pulling rope (23) reelsonto the rotating axle (23) to make the rotating axle (23) rotate in alow friction condition. During the operation of the exercising device,the seat (15) can slide along the supporting stand (13) with themovement of the body of the user.

With reference to FIGS. 1 and 7, the seat (15) can be securely held onthe supporting stand (13) in place with the pin (155) being insertedinto the bore (151) in the seat (15) and one of the holes (131) in thesupporting stand (13). The user sits on the seat (15), holds the firstgrip (291) by hand, steps on the pedals (16) and pulls the pulling rope(29). Because the seat (15) is positioned on the supporting stand (13),to pull the pulling rope (29) out of the housing (30) not only needs themuscles on the arms, but also needs the muscles on the abdomen.Therefore, a training effect to muscles on the arms and abdomen of theuser is simultaneously achieved.

With reference to FIGS. 1, 2 and 8, the user can stand on the pedals(16) and holds the second grip (42) by hand to pull the resilient rope(40), such that the muscles on the arms of the user can be trained in adifferent way. Accordingly, muscles of different parts of the user canbe trained with the exercising device, and the exercising device inaccordance with the present invention is versatile in use. In addition,the exercising mechanism (20) has an elementary structure, so thestructure of the exercising device is simplified whereby the cost formanufacturing the exercising device is low.

With reference to FIGS. 1 and 5, the second embodiment of the resistantdevice comprises a metal collar (25A), a magnetic resistance element(26A) and a resilient member (262A). The metal collar (25A) is attachedto an outer periphery of the flywheel (25). The magnetic resistanceelement (26A) is pivotally attached to the base (21) and corresponds tothe metal collar (25A) on the flywheel (25). One end of the magneticresistance element (26A) is connected to the cable (271). The resilientmember (262A) is mounted between the base (21) and the magneticresistance element (26A). The magnetic resistance element (26A) willprovide an attractive force to the metal collar (25A) on the flywheel(25), such that a resistance force will be provided to the flywheel (25)during the rotation of the flywheel (25).

When the adjusting button (28) is rotated, the magnetic resistanceelement (26A) will be pulled far away from the metal collar (25A) orpushed near the metal collar (25A) by the resilient force provided bythe resilient member (262A). Consequently, the attractive force appliedto metal collar (25A) will be changed, and resistance applied to theflywheel (25) is also adjusted.
